Lichens, usually greenish gray in color, are often most noticeable on tree limbs and shrubs during winter when there are less or no leaves. Lichens are a combination of a fungus and alga that support each other. They are not parasites attacking a plant.

To avoid lichens, keep your plants healthy. When they do occur, they can be picked off, advises the County Extension Office.
